T ENGINE VALVE/f,

Application. filed December 10, 1924.1;Seiia1No. 754,984..

To (HZ whom it mayc'oncern Be it known that 1, JAMES MOCU'MBER,

a citizen of the United States, residing at Kingwood, in the county ofPreston and State of \V est Viginia, have'invented a new and usefulEngine Valve, of which the following is a specification.

This invention relates to engine valves and aims to provide a novel formof valve. which will be noiseless n its operation, and

one wherein an air-tight connection between the valve and its seat willbe insured at all times, eliminating leakage to increase the power ofthe engine;

An important obj eot of the'in'vention isto, provide a valve which willhave a plurahty" of seats, the same being of a construction 7 wherebythe explosion caused within the i cylinder will act to force the valvecloser to its seat to eliminate leakage.

Another object of the invention is the pro:

vision of a valve constructed so that carbon deposits on the valvewillnot in any way act to decrease the efficiency of the valve.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the com} bination andarrangement of parts and in the details of construction hereinafter .de

scribed and claimed, it being understood that changes in the preciseembodiment 0f the invention herein disclosed, may be made within thescope of what is claimed, wlthout departing from the spirit of theinvention.

Referring to the drawing: e Figure 1 is a fragmenta'l sectional viewthrough the upper portion of an engine cylinder disclosing a valveconstructed in accordance with the invention as mounted in the headthereof. a

Figure 2 is a longitudinal sectional view taken at rightangles toFigurel.

Figure 3 is a perspective view of the valve forming the essence of theinvention.

Refering to the drawing in detail, the

reference character 5 indicates an engine cylinder in which the piston,6 operates, the

cylinder and piston being of the usual type,

and forming no' part of thepresent 111VI1-.

' the'push rod27 is'provided with a'pin28' tion. l r

The engine head is indicated at 7 and is provided with the usualcompartment 8 to accommodate the cooling fluid employed formaintainingthe engine in a cooled condition. This head is provided Withrecessed p rt e 9 f hich el g she n in th present drawing, whichrecessed portions accommodate the'valves formingthe essence. oftheinvention. As shown by Figure 1 of the drawing, a recessed portion isindicated at 9, the valve operating therein being indicated at 10, thesame being hollow so that the foroe of the explosion usually directed tothe under surface of'the head will bedirected' to the interior of thevalve to force it to its seat.

The valve is formed witha tapered upper surface indicated at 11'to whichthe valve stem 12 1s secured and as shown, this upper portion 11 isprovided with an eX- haust port 13 and an intake port 14, the exhaustand intake ports registering with the. exhaust and intake ports 15 and16 re-' spectively, that are formed in the engine head, manifolds 17being secured tofthe head for directing the fuel to the engine cylindersand directing the exhaust from the cylinders. 1

The reference character 18 indicates a peripheral flange which seats'at19 to insure a tight connection at this point, while the upper taperedportion 11 of the valve seats at-20, to further insurea'tight'connection hetween the valve and the recessed portion in whichit is positioned. 1 I

Mounted on the valve stem 12 is a coiled spring indicated at 21 that hasits lower end bearing against the head of the cylinder while theoppositeend'thereof ispositioned in the cap 22 that is'held againstmovement on the valve stem by means of the pin 23. At the upper end ofthe valve "stem is an arm indicated at Q lwhich extends laterally andisengaged by the forked extremity 25' of the rocker arm 26 which ismounted in the usual manner, on the engine'head.

Contacting with the outer end of the rocker arm islthfusual push rod 27that moves in vertical planes so that as the rocker arm 26 is movedupwardly, an oscillating movement will be imparted to 'thc valve proper,through the mediumof the arm 24..

In order thatthe rocker arm 2'6'will be returned to its initial positionafter it has been moved to op rate the valve member,

that moves in the'slot-29 From the foregoing it will be as "that due tothisconstruction an oscillatory movel .ment will be imparted to thevalve to move he ietake, and ethane? p t's thereef alter nately-intovregistry With the intake and exhaustv portfeof the cylinder heacl tocon.- trolt-he passage of fluid and exhaust gases having a recesseclportion and having inlet and exhaust openings formed: therein, a valve"including a circular body portion, having a peripheral flange, saidflange having an inclined: upper edge, the lower edge of the walllof therecessed portion being beveled to receive the inchned upper edge at thetween the valve andflrecessed portion in which the valveoperates,"and-'lneans for opmating. the valX "ei In testimony that Iclaim the foregoing V flange to provide a flu-id' -tight connection bcasmy own I: have. hereto a-ffixed my signature.
